沒有路線匹配缺少必需的鍵：[：永久鏈接]

Question

嗨我正在軌4.2.5,紅寶石2.3.1p112。

我面臨這個錯誤缺少必需的密鑰永久鏈接。

錯誤消息：

No route matches {:action=>"show", :controller=>"product_categories", :requirements=>{:id=>/[^.?]/}} missing required keys: [:permalink] 

我的視圖（錯誤的）

= link_to top_level.name, product_category_path,:permalink => top_level.permalink, :title => "Shop Designer Brands in #{top_level.name}", "data-tracking-event" => "PCInHeader", "data-label" => top_level.name, :class => "gaevent" 

我的路線

match "/catalog/*permalink" => "product_categories#show", :as => "product_category", :via => [:get], :requirements => { :id => /[^.?]/ } 

幫助了我去解決這個問題？

Answer 1

通permalink哈希作爲參數的URL幫手

= link_to top_level.name, product_category_path(permalink: top_level.permalink), title: "Shop Designer Brands in #{top_level.name}", "data-tracking-event" => "PCInHeader", "data-label" => top_level.name, :class => "gaevent" 

希望幫助！

Answer 2

根本就product_category_path（永久：永久）作爲第一個放慢參數被認爲是Id，然而在這裏，你需要永久鏈接，而不是ID
